Material deposition apparatus for a planting unit

摘要

Apparatus adapted for use with a disk type planting unit or opener assembly for depositing material in a furrow formed in the ground thereby. The disk type planting unit or opener assembly includes a disk supported for forward movement through the ground for forming the furrow, the disk being oriented at a small acute angle with respect to the forward direction and having a generally rearwardly facing disk surface. The apparatus includes a material delivery member having an inlet opening for receiving the material, a lower portion having an outlet opening for depositing the material into the furrow, and a conduit for the passage of the material between the inlet opening and the outlet opening. The apparatus further includes a runner extending forwardly from the material delivery member adapted to be located in the furrow in a steady state position wherein a lower portion thereof is positioned beside the rearwardly facing surface of the disk, for keeping loose soil from entering the furrow in advance of the material deposited therein. A support member extends forwardly from the runner for mounting the runner and the material delivery member to the planting unit or opener assembly at a forward location, such that during the forward movement, the runner will be urged by the support member toward the steady state position.
